Abstract
After the name of a signal line is entered, cells are arranged and, a channel to be wired therein is generated. After the completion of global wiring and minute wiring, a compaction process is performed. Here, the transistor density TD of an integrated circuit device to which the compaction process has been executed is compared with a standard value TDst. The compaction process is repeated unless TD>TDst, and terminated when TD >TDst. The time to terminate the compaction process can be judged from objective standards regardless of the level of a designer's skill, so as to keep the layout design of an integrated circuit device above a certain level.
